Misc / Open / Re: The demise of Classic Bikes
« on: January 08, 2017, 10:02:05 PM »
Interesting discussion. I started riding in the mid 70's and like many others have been riding ever since. I had a few SOHCs in the early/mid-80's when they were dirt cheap. I have two seventies bikes now - a 750F2 and a KH400 which yes, I bought for nostalgic reasons but mainly because I enjoy riding. The CB and KH give me very different riding experiences. I also have a modern bike which is used for commuting, two up touring etc but the older bikes give me more involvement in lots of ways - riding, fettling, polishing.

If riders younger than me, and yes the numbers are reducing, enjoy different riding experiences then classics will survive.

CB750 / Re: 750 F2 carb problem?
« on: August 29, 2016, 05:05:12 PM »
An update on the F2 carb front: a motorcycle tech I know who has been in the game since the late 70's spotted me fettling in the garage as he was passing by and reckoned with the right tools the no 1 floatbowl should come off without taking off the carbs - he was right. I took the bowl off, dropped the float out and the needle valve and gave everything a good checkover and clean and reintsalled - still the petrol peed out! Looks like the carbs will have to come off after all but I sent off for a new float valve from that nice Mr Silver to be on the safe side.

The good lady is away visiting family so before dismantling the carbs I dropped the float bowl again to try the new float valve - straight away comparing the old and new one it was obvious that the operation of the old one was nowhere near as good. Install the new float valve and bingo no more gushing petrol. it fired up easily and a quick ride showed everything back to normal! Time for a celebratory beer.

Thanks guys, the bike has been in regular use so I don't think it will be gummed up or stale fuel from being laid up and it's been running fine over the couple of years I have had it until now. I'll let you know how I get on.

CB750 / 750 F2 carb problem?
« on: August 07, 2016, 11:31:28 AM »
Seventy five miles into a ninety mile ride my F2 went on to three cylinders. Got home and number one spark plug was oily but sparking nicely and then realised that the carb on that cylinder was piddling petrol from the overflow. I did the usual thwack to the carb body but no joy. I am assuming it will be carbs off and a clean out but before I do that anybody else had a similar problem and what was the outcome?

CB750 / F1/F2 exhaust collars

Are the exhaust collars on the 750 F1 and F2 the same please? I'm sure lots of you will know the answer.

Hi Nano,

I'm in Exeter as well. Had a CB650Z until earlier in the year and now got a 750F2. I'll keep an eye out for you around town.

Top tip, had the same issue after leaving my F2 on the sidestand. Put it on the centrestand, fired her up with the tap off and when it started to die switched the tap on and hey presto - no leak. Brilliant!

New Member Introductions / Hello from Devon
« on: January 26, 2014, 07:35:18 PM »
Hello all,

My name is Pete and I live in Devon. I've owned a fair number of bikes over the years including a couple of 400/4s, CB650Z and 750 K2, K6, F2 and a Rickman CB750. I've just acquired a 1978 CB750F2 in pretty original condition to sit alongside my 1997 Blackbird. I'm a member of the VJMC and will be on the road with the 750 once the rain stops persisting down - so that will be on a couple of days in August!
